What happens during primary wastewater treatment? choose one: a. insoluble particles are removed by settling. b. microbes are added to oxidize organic compounds to carbon dioxide. c. the wastewater is pumped into drinking water reservoirs. d. the wastewater is chlorinated to eliminate pathogens.

The process that happens during primary wastewater treatment is:

A. Insoluble particles are removed by settling.

Explanation: Settling is an operation that removes suspended particles in the water to be treated.

answer: c. two haploid cells

explanation:

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
